INTERLOCKING-BLOCK STRUCTURE.

Specification of Letters Patent.

Patented Jan. 2,1912.

Application filed July 17, 1911, Serial No. 639,023.

The purpose primarily is to for m the blocks of glass which may be variously shaped, decorated and assembled, thus providing a variety of devices that are at once useful and ornamental.

In Figures 1 to 5 of the accompanying drawings I have shown blocks of square section which are constructed with special reference to the requirements of a built-up candlestick, Fig. 1 being a view partly in elevation and partly in section of a threesocket candlestick and Fig. 2 is an edge view thereof, also partly in section. Figs. 3 and l are sectional plans on the irregular lines 3-3 and M, respectively, of Fig. 1. Fig. 5 is a perspective view of the candlestick partly assembled, the remaining blocks being detached.

The invention consists essentially of six blocks which are arranged in three pairs, with the blocks of each pair paralleling each other and disposed at right angles to and interlocking with-the blocks'of the other two pairs. The other two pairs, comprising what I term the second and third pairs, are preferably of the same size soas to form an assemblage-of conventional design, with the blocks of the second and third'pairs interlocking with each other and with the blocks of the primary pair. The slight difference in the notching of the second and third pairs will be indicated hereinafter. One of the blocks of What I term the primary pair is notched to provide a hold for the fourblocks of the second and third pairs, and the second and third pairs are in turn notched to provide a passageway for the second block of the primary-pair, which second block is unnotched and may be termed a key block as it holds all the blocks in place. l v p In the adaptation shown, the blocks are square in cross section. and block 2 of the primary pair consists of a square upright portion of a candlestick stem, one, of such blocks being arranged at either side of the central upright portion 8, the whole supported by base or foot 5 with which it has the pin and socket connections 4:.

6 is the companion for block 2, .the same being the key block for the assemblage as will presently be described, blocks 2 and 6 constituting the primary pair to which reference has been made.

The corner-like face of block 2 is formed with two notches 7 arranged one above the other, and embracing block 2 at these notches are blocks 8 of the second pair, and crossing blocks 8 and notched to interlock therewith and with block 2 are blocks 9 of the third pair. As shown, blocks 9 project be yond blocks 8, and blocks 8 and 9 are so jnotch ed that when assembled they form a passageway for the key block, and when the latter is moved longitudinally thereinto the several blocks are held firmly interlocked.

Notches 7 in block 2 are of plain V-shaped formation, as shown in the lower portion thereof in Figs. 1, 2 and 5 (to which lower notches additional assemblages of blocks may be applied if desired). Notches 7 embrace blocks 8, and the latter are notched in one direction at 8 to receive blocks 9, and are also notched at 8 to form a passageway for the key block 6. Blocks 9 are formed each with two notches 9, one of said notches embracing block 2, and the other for receiving the key block 6.

In the double formation shown at each side of Figs. 1 and 5, block 6 is elongated with the lower portion thereof performing the functionof a key, and the upper portion 6 corresponding to the primary block 2 and provided with notches 7, the same as in block 2, to form the primary support for other pairs of blocks 8 and 9 (notched respectively as above described; and held locked by a final key block 10, the latter serving as a candle socket 11. Obviously, by employing a series of compound blocks likethc blocks 6 6, the formation may be extended indefinitely.

The blocks are not necessarily square in cross section, as various shapes may be employed, and it'will be understood that the interlocking principlemayfbe utilized in forming various objects.

YVhile the blocks may be of any desired material. the invention is designed with special reference to forming them of glass, from which a great variety of shapes and ornamental eflects may be produced, theuses thereof being by no means confined to the adaptations here shown.

I claim 1. The combination of a base supported upright having two notches in one side thereof-one above the other, four blocks arranged in pairs of two with the blocks of each pair; crossing the blocks of the other pair and notched .to embrace the same, the blocks of one pair notched to embrace the notched upright and the blocks of both pairs notched to embrace a second upright, an unnotched second upright inserted in the notches of the crossed pairs of blocks and supported thereby on the base-supported up right, and an object holder sustained by the second upright.

2. The combination of a central base-supported upright, two supplemental uprights-one at either side of the central upright with each supplemental upright formed with two notches on its outer side one above the other, two duplicate sets of blocksone set cooperating with each supplemental upright, each set consisting of four blocks arranged in pairs of two with the blocks of each pair crossing the blocks of the other pair and notched to embrace the same, the blocks of each pair notched to embrace the appropriate notched supplemental upright and also notched to embrace a second upright, two unnotchcd uprights-one for each set of blocks, each unnotched upright inserted in the notches of the appropriate crossed blocks and supported thereby on the supplemental uprights, and object holders sustained by the said second uprights.

' In testimony whereof I affix my signature in presence of two witnesses.
